Suspended ceiling sprinklers
Suspended ceiling sprinklers
(OP)
Hi all,
we have to do calculation for a sprinkler system. But we have upright sprinklers in concealed spaces below ceiling with in the sprinklers protecting the room ( as in FIGURE 8.14.19.3.3 of the NFPA 13 -2003 ed) . For the hydraulic calculation shall i have to consider all these suspended ceiling upright sprinklers with the pendent sprinklers which corresponds the sprinkler area of operation. This doubles the quantity of the foreseen activated sprinkler and flow rate.
Thanks in advance for all your comments.

RE: Suspended ceiling sprinklers
In my understanding of your question, it sounds like if you calculate the highest demanding sprinklers, you can omit the sprinklers above or below the ceiling. Whichever is less demand.
Again, I'm not understanding the question so read that section to help clarify
